Using Directory Opus 5

This section gives you a short tour of Directory Opus 5. It
describes the operation of the program when using its default
configuration. Other configuration options are described in later

Aborting Operations

Before using the program, it is important to know how to abort an
action. Most functions can be aborted once they have begun. This
can be quite useful if you accidentally start deleting the contents of
your hard drive.

To abort an operation, select the 'Abort' gadget shown in the file
Lister. Do not be alarmed if the action does not abort immediately;
some functions such as copy, may have to finish with the file they
are working upon before exiting.

Because Opus 5 uses extensive multitasking, it will often internally
spawn another task or program to perform your selected action.
Or, the selected action may be spread over a number of Opus 5's
internal tasks. For example, when de-archiving, Opus 5 will
spawn your selected archiver, for example, LHA, with the
arguments to perform that job. After this Opus 5 will return to
monitoring its main screen. To abort such actions, it will be the
LHA task you must abort not Opus 5.

Opus Context Sensitive Help

Directory Opus 5 provides extensive context-sensitive help.
Simply move the mouse pointer over an object in the current
window and press the Help key. This will lookup the object in the
Opus 5 AmigaGuide-based help system and display the details of
the object, button, or command pointed to by the mouse pointer.

If the mouse pointer is over an Opus 5 Custom Button, the help
system will display information on the first command attached to
that button. Of course, Opus 5 can only show details of its own
internal commands. It cannot show details for script files or calls
to AmigaDOS programs.

Directory Opus 5 Components

As discussed in the introduction, Directory Opus 5 consists of a
number of inter-related objects, each running as its own task or
process but communicating with the other objects as required.

The main objects of the Directory Opus 5 system are a base
window, called the Opus 5 Main Window, plus any number of
the following objects:- a window displaying files and directories,
called a Lister ; a window displaying custom buttons, called a
Button Bank; secondary requesters for functions such as
DiskCopy and Format; and from time to time, various windows
used to edit and adjust the configuration settings or other
operational parameters of the Opus 5 system.

This may all seem a little complicated at first, but in practice it is
not! It just uses the capabilities of the Amiga to allow you to do
several things at once, if you want. In reality you will find the
power and flexibility easy to master.

The Opus 5 Main Window

When Opus 5 is started, it first opens its main display window.
This is the handle by which you initially access basic Opus 5

This window, and its underlying process, provides similar
functionality to that of Workbench. As discussed on page 26, with
Opus 5 you no longer even need to run Workbench at all and can
use the Opus 5 Main window as a replacement for the standard
Workbench window.

Like Workbench, the Opus 5 Main Window shows icons
representing the disks and volumes available. Once you have
mastered using Opus 5 itself, you may also wish to leave out other
icons for your favourite files, directories and programs.

You can select to open the Opus 5 Main Window on its own
custom public screen, on the Workbench screen, or on any public
screen available in your system. You may also use the Opus 5
Main Window in place of Workbench as discussed elsewhere.

Program Application Icons

Opus 5 can display the AppIcon images which application
programs may open as special handles on Workbench. The
display of these may be controlled by a switch in the Environment
requester as discussed later. If you turn this option on, Opus 5 will
hear about these events from the Amiga OS whenever a program
attempts to add these to the Workbench display.

Selecting Icons

To access any icon displayed on the main window, simply doubleclick
on the icon with the left mouse button. This will open the
volume or device and read its contents into an Opus 5 file Lister

Alternatively, you may use the keyboard to select and activate the
icons as follows:-

  • the SPACE key toggles keyboard selection mode,
  • the Arrow cursor keys move the highlight,
  • the RETURN key activates the selected icon.

Leaving Out Icons

If you wish to leave out other icons representing files, programs or
directories, you can highlight the icon and select Leave Out from
the Icons menu, select Leave Out from the entry's RMB pop-up
menu, or more simply drag and drop the item(s) onto the main
window from a file Lister display. Left out icons will display a
small arrow image to show that they are left-outs. To put icons
away, highlight the icon(s) and select Put Away from the Icons
menu or the icon's pop-up menu.

+Unlike Workbench, when you 'leave out' files, the icon images
are still visible in their original directory.

Icon Pop-up Menus

Each icon displayed on the Opus Main Window has special, sticky ,
pop-up menus, accessed by clicking the right mouse button over
the icon. These menus contain a selected set of commands
depending on the object to which they are attached, whether Disk,
Drawer, Group, or left out program. These pop-up menus are also
available on icons in Icon or Icon Action mode Listers and, if
activated, are also available on files in Name mode Listers.

In reality, these pop-up menus are Filetype specific and are
enhanced by the Opus 5.5 Filetype recognition system. From
Filetypes you may easily add new menu functions according to the
type of file. For example you could add special menus to any LHA
file as shown below.

Program Groups

On the Amiga, the concept of Program Groups is unique to Opus 5.
Instead of having to leave out all your favourite applications on
the main window, Opus 5 gives you an easy way to organise your
files by allowing you to create custom drawers called Groups. In a
Group drawer you can collect your favourite applications for
immediate access.

As an example, you could create a Group called 'Graphics' and
store in it programs such as DPaint, Brilliance, Photogenics or
other painting programs. Another example would be to create one
or more groups and collect all your related Internet applications in
one place. One group called 'Net' could be used to reference
applications such as AmiTCP scripts, another called 'WWW' could
hold assorted web browsers, and yet another could hold mailers
such as Thor and other Internet utilities.

Instead of having to search all over your hard disk for each
program, you could then simply open the 'NET' group, for
example, and double-click on the required program to start your
Internet connection and access the World Wide Web.

To place applications in a specific Group drawer, open an Opus 5
Lister showing the application's current directory then drag and
drop the application icon into the Group window.

For efficiency, Opus does not copy the actual icon or program to
the group drawer but only preserves a reference to the actual icon.
If you edit an icon in a Group, you are actually editing the original
icon. When you double-click on icon in a Group, you are
effectively double-clicking on the real icon in its real directory.

Not all icons may be placed into a Group drawer. If a file
does not have an associated TOOL or PROJECT icon, it cannot be
placed in a Group drawer. Also, you cannot place other drawers
in a Group drawer.


Access to other main Opus 5 functions is provided by global
menus attached to this window. (See The Global Menus on page

File Listers

Lister Popup Menus

Popup menus have a new shadow look while the basic functionality has been enhanced by additions to the various menus. Additions to the filetype-specific RMB 'sticky' popup menus include:-

  • Copy to Desktop in all modes. (See Opus Desktop below.)
  • Open in New Window in name mode for directories which opens a new Lister for the selected directory.
  • Clean Up to Lister popup in Icon modes
  • Project files have a new Open With.. in the file popup menu, which lets you select an application to open the file with. By default, Opus remembers up to the last 10 programs chose but this may be adjusted from the Environment /

Miscellaneous settings.

  • The delay before opening the popup sub-menus may be adjusted from the PopUpDelay value in the Environment / Miscellaneous settings.
  • Sub-Menus - Lister menus can now have sub-items. You can effectively have three levels of menu commands. In the menu editor, what were items and sub-items have been shifted one place to the left to allow an increased menu depth.

New Lister Format Editor Features

  • The Free Space Gauge option adds a fuel-gauge to Listers, showing the proportion of space free on the disk. The colour for the 'bar' part of the gauge may be set from the Environment/Lister Colours section.
  • The display of the gauge can be controlled on an individual Lister or path basis from the Format Editor, or may be added as a global from the global format settings inEnvironment / Lister Default.
  • This lets you set which Listers you want the gauge to appear. For example, if you only want a gauge on the root directory of certain devices, turn it off in the default Lister format and then turn it on for those directories.
  • The Inherit option has the same effect as the padlock gadget; if turned on, sub-directories will inherit the format of the parent directory (when double-clicking on them in name mode). When turned off, unless a directory has a format defined for it, it will use the default format

Icon & Icon Action Mode Listers

  • The Filter Icons flag from the Lister Format is now ignored in the Icon modes so all icons are now displayed correctly.
  • Drag and drop in icon mode now ignores filetype settings and always copies (or moves) the dropped items.
  • Listers now automatically resize themselves when switching between icon and icon action mode.
  • Holding down the Ctrl key while double-clicking on a directory in an Icon Action mode Lister will cause the new directory to be read into the existing Lister instead of opening a new one.

Name Mode Listers

Proportional Fonts for Listers

Proportional fonts are now fully supported with name mode Listers. The selected font may be set in the Environment/Lister Display

Adjustable Field Sizes

The size of the Lister fields is set dynamically by Opus according to the width of the field's contents. However, you may now adjust the size of any field in real time by selecting and dragging the separators between Lister field titles. This feature allows you to resize a wide field such as 'Name' whe using long filenames so you may see the other fields more easily.

To restore a field that you have resized to dynamic sizing, double-click on the separator.

Field sizes are reset dynamically when you change directories. If you change field sizes in a given directory, the sizes in the specific directory will remain set until the directory goes out of the cache or until memory is flushed by Avail Flush or a low memory condition.

Remember, you can also re-order the Lister field titles and format of the Lister fields by dragging the field title themselves to the required position. For example, you could pick up an drag the 'Date' field to the left hand edge of the field titles and drop it on the Name field to rearrange the display.

Visible Sort Order

You may change the sort method for entries in a Lister by clicking on a field title. Opus now complements this ability with a visual indicator to instantly show you the order in which your files are sorted. A small triangle is displayed in field title bar to indicate the current sort field and sort order.

Inline Editing

You can edit an entry in the Lister by using the rename command (from a command, toolbar button or RMB popup menu). Or, you can activate inline editing mode in a name mode Lister by clicking on an item and holding the mouse button down for a few seconds. (The activation method of inline editing, if any, using left or middle mouse buttons can be set in the Environment / Lister Options settings.)

Edit the details as required and press TAB or SHIFT-TAB to move between fields. SHIFT-DEL and SHIFT-BACKSPACE are supported and delete from the cursor to the end of field or start of the field respectively.


Double-clicking on a program in Name mode runs it as an AmigaDOS program, with arguments, even if the program has an icon. Opus 5.5 would automatically run the program as a Workbench process if there was an associated icon. However, you may still run a program with an icon as a Workbench process from a name mode Lister if you hold down the shift key when you double-click on it.

FTP URL in Path Field

Entering the URL syntax of FTP://<arguments> in the Lister path field will launch Opus FTP in the current Lister. (See the OpusFTP section.)

Drag and Drop into a Sub-Directory

When enabled from Environment/Lister Options, you may drag and drop files directly into a sub-directory in Name mode. Moving the mouse when dragging files over a directory in a Lister (either the same Lister or a different one) will highlight the directory name. If you release the files over that directory, the defined filetype action will use that sub-directory as the destination path rather than the path of the Lister itself. If you have this option switched off, you can always activate it by holding down the SHIFT key while dragging. Note that this does not apply when dragging icons, only for files/directories from a name mode Lister. OpusFTP now also supports this function from a remote FTP directory to a local directory, but it is NOT supported on or between remote FTP directories.

Drag and Drop to Parent Directory

The Magellan II version complements drag and drop into a sub-directory by adding the ability to drag and drop to the parent directory of a Lister (in name mode only). This is done by dropping files on the left edge of the window (the hidden parent gadget). Note: This can be slightly difficult to perform with a normal Lister and is much easier if the fuel gauge is enabled.

Special Keys

The '0' key was actually predefined by Listers, and so could not be used to scroll to a file beginning with a 0. This is now changed (the '=' key now does what the '0' used to do)

Lister Snapshot

We have changed the 'Snapshot' terminology to avoid potential confusion. The Lister popup menu now specifies whether you wish to snapshot the Lister (its display mode or status and the position) or the icons.

Filetype Pop-up Menus

These Filetype specific menus are accessed by clicking the RMB
over any entry in the Lister, whether directory, file, or icon. These
are the same menus as those available from icons on the Opus
Main Window. (See Environment/Lister Options)

Lister Position, Display Format and Sort Order

When a new Lister is first opened, it will use the system defaults
for size, position, mode as defined in the current Environment,
unless you have previously done a snapshot of the size and
position (and mode) for the chosen directory path. If the Lister is
in Name Mode, the display format and sort order will also be
taken from the system defaults unless you have saved a special
format for this path. This behaviour can be refined further with
settings in the Environment/Lister Display and Environment/Lister

For Name Mode Listers, if a special path format has been saved for
the chosen path the Lister will adopt the display format and sort
method you have previously saved unless you freeze the Lister
format by using the lock gadget in the Lister title bar. If this is
selected, any special path formats will be ignored and the current
Lister format will be used.

Editing Display and Sort Order

The Lister format editor may be invoked from the Lister status
menu (Edit) or by a double-click of the right mouse button in a
Lister window if that option is enable in the Environment Editor
Lister Options. The format of each Lister may be changed

The display format used in each Lister can be made up of any of
the following fields, in whatever order you wish:-

File Name File Size
File Date Protection
Comment File Type
Version Owner
Group Net Access

+The version check understands version format used internally
for libraries and devices and also looks for the version string as
recommended in the Amiga Style Guide (defined as "$VER: Name
version.revision <(DD/MM/YY)>" ). If the version information in
the file does not follow the recommended standard, Opus may
report anomalous results.

The chosen display order is shown in the Display/Sort list with
the field by which the data is sorted tagged with a check mark.
You can move items from the Available list to the Display/Sort list
by clicking on them. Alternatively, if you click and hold a given
item, you can drag and drop it between the lists, and also drag it to
a new position in the Display/Sort list.

  • Entry Separation: Choose between a display with
    Directories shown first, files shown first, or a mix of files
    and directories, sorted in order as selected above.
  • Reverse Sorting: By default, the display is sorted in
    alphabetical order, or, if the item starts with a number, then
    the item is sorted in numerical order. Tick this gadget to
    display the list in reverse order.

Normally, the Opus 5 file Listers will display all files and
directories in the selected directory. By using the filters you can
restrict the files displayed.

  • Filter Icons: By default, all the '.info' icons files are also
    displayed in the list. Check this gadget if you wish to not
    display these files.
  • Hidden: When checked, tells Opus 5 to NOT show any
    files with the 'H' or hidden bit set.
  • Show and Hide: These text fields allow you to select a
    pattern of files to show or files to hide. The pattern may be
    defined using the standard Amiga wild cards of '#' and '?'.
    For example, putting '#?.o' in the Hide field, will cause the
    Lister to hide any file ending in '.o'.
  • Reset to Defaults: Will reset the format to the current
    global system default setting. Saving this format will cancel
    and remove any previously defined special path format.

Save: Ties the defined format to the path displayed in the
Lister and permanently saves (snapshots) it for use
whenever the defined path is accessed.

+Saved formats are remembered forever and always override
the system default format unless the Lister lock gadget is closed. 
Use Reset to Default to clear and forget a stored format.
Use: Accepts this format for this Lister for the current
session Cancel: Abandons all changes

Dynamic Resorting

Since each Lister supports dynamic resorting, it is easy to change
the sorting method in a specific Lister on a temporary or
permanent basis. For example, you may wish to see the new files
recently added to a directory. To do this, double-click the right
mouse button over a Lister to bring up the format editor, select File
Date as the sort method, tick Reverse Sorting and select Use.
(Alternatively, if Field Titles are being displayed, simply click on
the Date field title.)

Special Formats for defined Directories

In some cases, you may often wish to define a specific display
format for a particular directory. For example, you may wish
normal directories to be sorted in filename order, but with a
'Downloads' directory, you may wish to see the latest files you
have received.

As from Opus 5.5, if wish to have a special format associated with
a specific directory (such as a Download or Incoming directory),
set this directly from the Lister format editor then select Save, and
the chosen format will be permanently stored for whenever you
next access this directory. (See page 93 for more details.)

Lister Field Titles

From the Environment/Lister Options settings, you may select to
display the names of the fields shown in a Name mode Lister.
When these are active, clicking on the name of the field will
dynamically resort the Lister, alternatively in ascending or
descending order by that selected field.

Lister Toolbar

Immediately beneath the status bar, is an optional toolbar showing
small graphic images or icons. Each of these images is actually a
normal Opus 5 action button for which you may define separate
actions for left, middle and right mouse clicks.

By default, Opus 5 uses the file Buttons/Toolbar, but you may easily
define your own Toolbar. The images and actions of the Toolbar
buttons can be edited from the Editing the Lister Toolbar on page
182 for more details. For those who wish to experiment or
extensively customise their Lister display, Opus 5.5 has a new
internal command, Set Toolbar, which allows you to load a new
toolbar of your choice into any given Lister.

+In Opus 5.5 the Lister window (or button window) no longer
needs to be active in order to see right and middle mouse buttons. 
Clicking RMB or MMB over a Lister toolbar icon will generate the
associated RMB or MMB command function without activating
the Lister window itself.

Directory Path

At the bottom of the Lister display is a string gadget which
contains the full directory path. To go quickly to a specific
directory, you may enter the full path in this box and press return.
Opus 5.5 adds a history to the string gadget. Activating the string
gadget and pressing cursor up or cursor down will scroll through
the previous entries.

Hidden Parent Button

Each directory window contains a hidden Parent button on the left
hand outer edge of the window area. From any Lister in Name or
Icon Action modes, when you click the left mouse button on the
left-hand window border, Directory Opus 5 will display directory's
parent, if it has one. Alternatively, the button second from the left
in the default toolbar provides the functions for Parent and Root.

Lister - Icon Mode Display

Icon Mode provides a simple 100% compatible Workbench style
graphical display where files are displayed by their associated
icons. It is best used for running PROJECT applications which can
often be run more easily from their associated icons, or for quick
access to a new disk.

In Icon Mode, the Lister window behaves more like a standard
Workbench window. It does not have the status bar and toolbar,
nor its associated gadgets, only a standard window display.

Icon Mode is not designed to be used for extensive file
manipulation. If you wish to do this, switch to Name Mode.
However, you may still easily copy files using the simple drag and
drop operation.

The prime purpose for Icon Mode is to provide extra compatibility
with a standard Workbench display. In Icon Mode, when you
double-click on a PROJECT or TOOL icon, Opus 5 will launch the
application as if it had been run from Workbench. Otherwise, the
normal Opus 5 rules apply and Opus 5 will look at the file type
and follow the instructions you have provided under the
particular Filetype definition. (See Filetypes on page 139).

These different modes of operation can be seen by using the
master Opus 5 disk as an example. In Name Mode, if you doubleclick
on the InstallOpus5 icon on the master Opus 5 disk, Opus 5
will call the text viewer and display the script file as text. In Icon
Mode, because the InstallOpus5 is actually a PROJECT icon, a
double-click will run the Installer program with the InstallOpus5

In Icon mode, there is no concept of SRC or DEST Listers. Many
Opus 5 buttons and command do not work in this mode. Icon
mode is designed to emulate the old Workbench display. If you
need to have access to Opus functionality, either use Name or Icon
Action modes.

+Once you switch to Icon Mode, you lose the Lister status bar,
toolbar and associated menus. To return to Name Mode or Icon
Action Mode, use the RMB pop-up menu or the global menus and
select Lister/View As/Name.

Lister - Icon Action Mode Display

Icon Action mode is new for Opus 5.5. It combines the functions of
Name mode with an icon display. Since there are SRC and DEST
Listers, all the standard Opus internal commands work for Icon
Action mode on or between the active Listers, plus you have
extended drag and drop control using icons not just filenames.

Both the Icon and Icon Action modes allow you to have a
background pattern or picture in the Lister window.

If you double click on a drawer or directory icon in either Icon or
Icon action modes, a new Lister will be opened using the current
display modes unless the directory has a stored snapshot, in which
case the stored mode will be used. The position for the new Lister
will be the last used position or the snapshot position depending
on the settings in Environment/Lister Options.

If you hold down the left ALT key when you double-click on a
directory icon, the parent Lister will be closed automatically when
the new Lister opens.

Using the Listers

A Lister is used to display the list of directories and files in a
selected directory. You may also display the list of available
devices and assigns, or internal Opus 5 cached directories.
Custom modules and ARexx handles can also use Listers.
In Name or Icon Action mode, most actions and commands apply
only to the highlighted items in the list or highlighted icons,
although some commands, such as MakeDir, obviously, act to
create a new directory in the current directory as shown in the

Actions such as Copy, CopyAs, Move etc, act between a Lister
defined as the Source (SRCE) and a Lister defined as a Destination
(DEST). If you are using a multi-windowed multi-Lister display,
be careful that you have set the SRCE and DEST Listers correctly
before you attempt a semi-destructive action such as Copy, Move,
Delete and so on.

Actions selected from the Toolbar or pop-up menu in a particular
Lister act only on that Lister. Actions selected from Button Banks,
act on the defined source Lister or between the source and
destination Listers depending on the particular command or

Using a Mouse with a Lister

Activating a Lister

Single left-click on the Lister window title to activate the Lister

Left-click on status bar to make the Lister the source (SRCE).
SHIFT left-click on status bar to make the Lister the destination

ALT left-click on status bar turns the Lister OFF.

CTRL left-click on status bar toggles the LOCK option. This
toggles a SRCE to locked SRCE! or DEST to locked DEST!.

Depending on the settings in Environment/Lister Options, a double
right-click over a Lister can bring up the Lister Format Editor.

Moving Around

If there is more information available than will fit into the Lister
display, either horizontally or vertically, a limited display will be
presented. Use the window's horizontal or vertical scroll bars to
reveal the rest of the display.

Alternatively, you can also scroll up and down, and left and right,
by holding the right mouse button and moving the mouse. These
actions are available in all Listers irrespective of the display type.

Selecting Files and Directories

To select or highlight a file or directory, simply click on it with the
left mouse button.

To highlight multiple items, click and hold the left mouse button
and drag downwards or upwards to select the adjacent items.

Drag and Drop

Dragging selected items horizontally allows you to pick them up
and move them out of the Lister. You can then drop them either in
another Lister or on the Opus 5 main window, and even on other
objects including the various editors. This is called Drag and Drop.

Specifically, to drag and drop, select one or more files and/or
directories, and either

move horizontally outside of the window while holding the
button down
press right button while holding left button. If the Lister
already has files selected, use ALT left-click to "pickup" the
currently selected files.

Unless otherwise defined, drag and drop of a file copies the item to
the new location. For consistency, normal drag and drop
operations on a directory perform the same copy function. The
default action for drag and drop for all internal Filetypes is to
Copy the file, but, this can be overridden by user-defined settings.


Double-click on a directory to enter and display that directory.

Drag and drop a directory to copy the directory to the new location,
or leave it out if dropped onto the main window.

SHIFT drag and drop of a directory does not copy the directory but
displays the contents of the directory in the destination Lister.
(Actually, it is holding down the SHIFT key when you drop the
directory which does the trick!) SHIFT double-click on a
directory to open up a new Lister for that directory.

SHIFT ALT double-click on a directory to split the current Lister
display and open a new directory Lister.

+These actions for directories can be further defined by using
the special Opus "directory" Filetype. See Filetypes on page 139.)

Double Click Power!

Some of the power of Opus 5 is revealed by a simple double-click
on a file. In Opus 5.5 we have extended the double-click system
depending on the Lister mode, either File or Icon (or Icon Action)

Name Mode - Double-Click

When you double-click on a file Opus 5 examines it to see if it
can identify the type of file. If a file matches a previously userdefined
Filetype, for which the appropriate function has been
defined, the function is executed.
If a file does not match a user-defined Filetype, it is tested
against the internal Filetype definitions, which are as follows:-

Filetype Function
Executable Program Run
ILBM picture Show
Picture (DT) Show (via datatypes)
ANIM Animation Show (plays animation)
8SVX sound Play
Sound (DT) Play (via datatypes)
Icon Display IconInfo
Opus 5 Buttons file LoadButtons
Opus 5 Environment file LoadEnvironment
Opus 5 Options file LoadOptions

If none of these match, the action taken depends on the setting
of Options/Miscellaneous/Filetype Sniffer. Opus 5.5 provides a
new Automatic Filetype Creator to assist you in creating and
testing file types. If the Filetype sniffer option is selected, Opus
can examine ("sniff") the file in greater detail and install or
create a new Filetype for this type of file. (See Filetypes on
page 139.)

Otherwise, the SmartRead function will be called. This will
display the file as ASCII (with or without ANSI sequences) or
in hexadecimal, depending on its contents.
+In a Name Mode Lister , if you wish to check how Opus
recognises a specific file, add "File Type" to the display format.

Name Mode - SHIFT double-click

If you hold down the SHIFT key and double-click on a file,
Opus looks to see if the file has an associated icon and if so will
perform a double-click on that icon. This allows you to run
many programs and installer scripts directly from Name Mode
but through the project icons just as if from Workbench.

Icon or Icon Action mode - Double-Click

A double-click on an icon acts the same as Workbench, running
the project or tool as defined in the icon.

A SHIFT double-click in Icon or Icon Action mode has no
special significance unless more than one icon has been
highlighted (by holding down the SHIFT key and highlighting
multiple icons or drag selecting icons). In this case, a SHIFT
double-click will act the same as Workbench and search the list
of highlighted files to find the first TOOL, run this program
and feed to it the list of the other PROJECT files.

Clipboard Cut and Paste

Opus 5.5 now fully supports the Amiga clipboard. You can now
copy the displayed text from any string gadget such as the Lister
Directory Path using right-Amiga-C and paste this into another
gadget (or any other program which supports the clipboard) using
right-Amiga-V. Remember all Opus string gadgets support copy
and paste.

Support is also provided directly in Name Mode Listers. You can
directly copy the list of highlighted files to the clipboard with
right-Amiga-C. This copies the full path of the files to the clip.
(e.g. work:smeg/filename). If you use right-amiga-shift-C, only
the filenames themselves are copied, not the full path name.

Using the Keyboard with a Lister

When a Name Mode Lister is active, the cursor keys or keypad
cursor keys may be used to scroll the Lister display up, down or
left or right. Pressing SPACE toggles a special keyboard selection
mode. In Name Mode, the cursor keys may be used to move the
highlight up and down the list and the following sequences may
be used. In Icon modes, some of these key sequences will
selectively highlight icons in the Lister, others do not apply.

Key Function

Home / CTRL cursor up top of list
End / CTRL cursor down bottom of list
Pg Up / SHIFT cursor up up one page
Pg Dn / SHIFT cursor down down one page

Other key sequences include:-

TAB activates the next (non-busy) Lister.
SHIFT TAB activates the previous (non-busy) Lister.
RETURN (in keyboard selection mode) toggles selection
status of a file. In non-keyboard mode, it activates the path
field at the bottom of the Lister.
Enter (in keyboard selection mode) performs the same
action as a double mouse click.
SHIFT-ESCAPE closes the Lister.

Other key functions include:-

Del Format Editor
/ or BACKSPACE Parent ***
: or ; Root ***
* Select
( All
) None
- Toggle
+ DeviceList
(*** plus SHIFT to open a new Lister)

Quick Access to a File Name in Name Mode

To scroll quickly to the first file entry starting with a particular
letter, press that letter; the list will scroll as close as it can get to the
first entry. Press a letter in conjunction with either SHIFT key to
scroll to the first Directory beginning with that letter.

Extended Key Selection Gadget

For those large directories and CDROMs where more than one key
is required to choose a specific file, Opus 5.5 adds an extended key
